Abstract

L'invention concerne un câble optique (100) destiné à la communication comprenant au moins un élément de retenue (2) imperméable à la propagation de l'eau ainsi qu'un procédé de fabrication dudit câble optique (100). Le câble optique (100) comprend, en plus de l'élément de retenue (2), au moins deux éléments de transmission (3) logés dans l'élément de retenue (2), ainsi qu'un fil gonflable dans l'eau (4) logé dans l'élément de retenue (2). Le fil gonflable dans l'eau (4) est sélectionné en fonction de l'équation (I) suivante, dans laquelle VW représente le volume du fil gonflable dans l'eau (4) après gonflement lors du contact avec l'eau ; V représente le volume libre total dans l'élément de retenue (2) ; k représente une constante = 180, R représente une constante = 1,4 ; et Vt représente le volume libre pour chaque élément de transmission (3). De manière avantageuse, le câble optique (100) est imperméable à l'eau et le fil gonflable dans l'eau (4) n'induit pas d'effets de microcourbure sur les éléments de transmission (3).
